Feel free to post up pictures of different setups. State your spring/shock combo, or coilovers, and tire size IF different from stock overall diameter.
Also, feel free to discuss about how a given setup rides/handles, just don't get off topic.

What are compression(aka bump) and rebound, and what do they mean to me?

What are compression(aka bump) and rebound, and what do they mean to me?
(Taken from a Koni USA SCCA presentation)
Rebound:
- Controls "sprung" weight aka the weight of the car held by the suspension
- Affects transitional control
- Controls spring and chassis oscillation
- Balances understeer and oversteer
- Add rebound to "loosen" an end, remove rebound to "stick" an end
Compression:
- Controls "unsprung weight" i.e. wheels, brakes, etc.
- Holds tire to the ground
- Increase to improve grip and turn-in
- Affects ride harshness
- Generally increase until car begins to "skate"
